CCL:G: ANN: fityk 0.8.0 - curve-fitting software

 Sent to CCL by: "Marcin  Wojdyr" [wojdyr|,|gmail.com]
 Hello,
 A few years ago we started to write a peak-fitting software, because we needed
 something more flexible than the program we were using that time (it was
 PeakFit).
 Now the program, called Fityk, is quite mature, so if you need to fit curves
 and analyse X-Y data, you may check it out.
 People usually use the program to fit overlapping bell-shaped functions
 (Gaussian, Voigt, etc.), but it can also fit polynomials or any other
 user-defined shapes.
 It's GPL'ed (free). Works on Windows, Linux, FreeBSD, etc., and with some
 problems on MacOSX.

 Fityk is reportedly used in crystallography, chromatography, photoluminescence
 and photoelectron spectroscopy, infrared and Raman spectroscopy and other
 fields.
 If there are any students with experience in programming and in one of the
 fields above, who would like to improve the program, they may apply to Google
 Summer of Code, see http://code.google.com/soc/ for details.

 Marcin Wojdyr
